Flexible Display Support Parts Spacing for Bending Stress Reduction

The patent applies parameter changes by optimizing the distance between the first support part and second support part to be 0.4mm or less. This specific parameter adjustment ensures that when the bending area is bent, the support parts are close enough to prevent crack formation while maintaining manufacturing feasibility. The precise control of this dimensional parameter resolves the contradiction between reliability and device complexity.

The patent specifies a precise parameter range of 0.4mm or less between the first support part and second support part when the bending area is bent. This parameter optimization achieves stress reduction in the bending area while establishing clear manufacturing specifications. The defined threshold provides a balance between achieving sufficient stress resistance and maintaining feasible manufacturing precision requirements.

The patent applies local quality by providing structural support specifically in the bending area through the first and second support parts positioned on opposite surfaces. This localized reinforcement maintains the flexibility needed for angle adjustment and visibility improvement while preventing crack formation that would reduce durability. The support parts are strategically placed only where needed in the bending region rather than throughout the entire device.
